Figure 3. . . Dendogram of the complete hepatitis B virus (HBV) genome isolated from Chacma baboon 9732, South Africa. Samples representative of all 8 HBV genotypes and primate hepadnaviruses are included. Samples are numbered according to their GenBank accession numbers, followed by their country of origin. The sample from baboon 9732 (boldface) clusters strongly with the subgenotype A2 isolates (bootstrap value 100). Letters along the right indicate genotypes. Values along branches are bootstrap values. Scale bar indicates nucleotide substitutions per site.
